Some ways to tell your parents you want to wear diapers are to email them, text your parents, write them a note or even just sit down and talk to your parents directly.
Tell your parents directly that you want to wear diapers and they may accept the fact you want to wear diapers or they may not.
Personally I would never tell my parents that I wanted to wear diapers and I would keep it a secret and just wear diapers without them knowing.
When I was a toddler I was dressed in just a diaper and shirt and also during my Kindergarten years my mom did put me in diapers for the rest of the summer because I had to wear diapers during the school year because I wet my pants.
So during the summer when I was 5 years old and almost 6 years old my mom dressed me in just a diaper, shirt and shoes.
I went in public like that to the store, doctors, etc and at home I was outside playing in just the diaper and shirt and shoes.
It felt great to me and I actually loved it.
When I have kids I"m gonna dress them in just a diaper and shirt and shoes and take them in public.
At home when it's warm they are gonna be in just a diaper and shirt and maybe socks just like the diaper boy Tommy below.
